Sorry to bother with ATI trouble again. Problem is that I've got a laptop with a Radeon HD 2300 (X2100; M71). This card is not supported through the ATI drivers themselves (for some, to me, unknown reason).Thing is, I installed sab4.1 with gnome and everything works fine, except for anything more than basic 2d graphics - and even they are a bit sluggish (esp. when it comes to videos or shoving windows around in a frenzy). I've tried to install the radeonhd drivers but to no avail. Tried fiddeling with xorg.conf settings for hours but nothing. Whenever I try to activate the acceleration I get a white screen with only a movable mouse pointer visible.I'm running ubuntu 9.04 parallel but would like to make the complete switch to sabayon. Jaunty works completely out of the box (ie no proprietary driver, but full screen video, compiz with all effects, (though not really "real" 3d apps, such as games)). Now, I don't really care about games not running, but I would like to be able to watch videos without stroboscopic effects and I've also become quite fond of my compiz gadgets.My actual question: Does anybody know where I could find out what canonical did to get these things running in ubuntu 9.04 (8.10 didn't work that way). I have to admit that I'm still pretty green when it comes to the inner workings of linux, but that's exactly why I want to switch to Sab and would like to get my graphics working.I would be greatful for any kind of help (simple link appreciated, complete work-through and I would start to build a temple in your honour).CheersJack

You could try to copy your xorg.conf from ubuntu to sabayon (don't forget to backup your original working sabayon version). That way you could test your working ubuntu settings in sabayon. The opensource driver should be available in your sabayon install, and the xorg settings should be the same between sabayon and ubuntu...

But that doesn't work. My xorg.conf under ubuntu has only the identifiers for "Device", "Monitor", and "Screen". No options, no nothing - even though I'm using an external screen when at home. That's just my point. Ubuntu seems to be working differently. Mouse and Keyboard aren't even mentioned in the xorg.conf, though I'm using internal touchpad, external mouse, wacom tablet, external keyboard. Any other ideas?

Thanks Fitzcarraldo. Yes, tried radeon and radeonhd separately (uninstalled each one before reinstall and uninstalled the ati rubbish). Still doesn't work. Guess I've got a bit of a quirk somewhere.But, quite apart from me getting my machine running (which is actually not why I started the thread ).

Is there anyone who could explain to me, how Ubuntu manages to make everything run without using the xorg.conf? Not even openSUSE's (which are supposed to be brilliant at recognising hardware) latest liveCD managed to configure my system correctly.(I have to admit that I was cheeky enough to pose the same question on the ubuntuforums.org page, but so far didn't get a reply. So, maybe there isn't an easy answer.)
